Build System Migrator Skill

Migrates build systems to modern alternatives, handling build file conversion, plugin migration, and CI/CD integration.

Purpose

Enable build modernization for:

• Build file conversion
• Plugin migration
• Dependency management migration
• CI/CD integration
• Cache optimization

1. Build File Conversion

• Convert build configurations
• Migrate between tools
• Preserve build logic
• Handle custom tasks

2. Plugin Migration

• Map plugin equivalents
• Configure replacements
• Handle custom plugins
• Document gaps

3. Dependency Management Migration

• Convert dependency declarations
• Handle version management
• Migrate lockfiles
• Manage repositories

4. CI/CD Integration

• Update pipeline configurations
• Adapt build commands
• Handle caching
• Optimize parallelization

5. Cache Optimization

• Configure build caches
• Set up remote caching
• Handle cache invalidation
• Optimize cache keys

6. Incremental Build Setup

• Configure incremental builds
• Handle change detection
• Optimize rebuild time
• Manage artifacts
